Stop Guessing. Plant by Soil. SoilIQ™ tells you when to seed, plant, water, mow, protect, or wait, using the two numbers that actually decide what happens in your ground. Air temperature tells you how the day feels. Soil temperature and soil moisture decide whether seed germinates, whether roots grow, whether a pre-emergent barrier holds, and whether today's watering helps or hurts. KNOW MY LAWN Build your Lawn Profile with grass type, sun exposure, irrigation, soil type, drainage, foot traffic, current condition, and a custom lawn name. Today's Lawn Read combines your Lawn Profile with soil data and forecast trends into one recommendation on the Today tab. Tap it to see why it triggered and what to do next. SOIL AWARE WATERING The same moisture reading means opposite things in sand and in clay. SoilIQ measures root zone moisture against your own soil's wilting point and field capacity, so dry means dry for your ground. Forecast rain is weighed against evapotranspiration and weighted by probability, so a light chance is not banked as a soaking. When the root zone is holding all it can, SoilIQ tells you to wait. SOILIQ CALCULATOR Plan what to buy. Measure what to apply. - Product Rate Calculator - Nitrogen Calculator - Grass Seed Calculator - Mulch, Soil & Sand Calculator Save calculations to your Journal, share image cards, or log them as lawn activity. LAWNIQ LawnIQ™ is a soil-powered lawn advisor built into SoilIQ. It turns soil temperature, soil moisture, forecast trends, your lawn profile, and recent activity into clear guidance. Use LawnIQ to understand: - When to mow - When to water, and when to wait - When to seed or overseed - When heat stress may become a concern - When rain may change your plan - When pre-emergent timing windows may be approaching LAWN ACTIVITY & FIELD JOURNAL Log mowing, watering, overseeding, fertilizing, aerating, pre-emergent, rain, field notes, photos, and seasonal observations. SOIL TEMPERATURE AT MULTIPLE DEPTHS Readings at 2, 6 and 21 inches, calculated to exactly those depths. Seeds germinate near the surface. Roots live below. 14-DAY SOIL FORECASTS Soil temperature trends for seeding, planting, watering, and frost protection. HISTORICAL GDD TRACKING Tracked crop Growing Degree Days calculate from the actual planting date using historical weather data, not just the forecast. PLANTAI FOR 160 CROPS PlantAI™ asks two questions before calling a crop ready: is the soil warm enough today, and is enough season left to finish before frost. Home garden crops come first, field crops in their own section. Crops started from seed get a verdict. For the rest, SoilIQ says so plainly rather than inventing an answer. SAVED LOCATIONS & PROBE CALIBRATION Track conditions across your lawn, garden, plot, farm field, or client site. Calibrate readings against your own probe, per location and depth. APPLE WATCH, SIRI, WIDGETS & LIVE ACTIVITIES Check soil temperature from your wrist, ask Siri without opening the app, and pin readings to your Home Screen, Lock Screen, and Live Activities. PRIVACY-FIRST No account required. Your location is used only to fetch soil and weather data. SoilIQ does not sell your data, and core features work offline from cached readings. Export your full history at any time, because your records are yours.

WatchBarometer turns air pressure into useful context on iPhone and Apple Watch. Highlights: - current sensor pressure or sea-level-normalized pressure - short-term weather trend from pressure changes - pressure history from six hours to the complete timeline - comparison of raw and altitude-aware sea-level pressure - GPS altitude history with optional barometer refinement - focused measurement sessions - widgets, Live Activity, and Apple Watch complications WatchBarometer uses the device's running barometer stream, GPS altitude for sea-level context, and read-only HealthKit samples only when Apple already includes barometric pressure metadata. Important: - high- and low-pressure classifications use compensated sea-level pressure only - raw sensor pressure is not misleadingly classified across different elevations Built for weather watchers, hikers, and anyone who wants to understand pressure, trend, and altitude instead of seeing just one number.
